Inadequacy of gestational weight gain during high-risk pregnancies is not associated with household food insecurity.

BMC Pregnancy Childbirth 2021 Jun 29;21(1):460. Epub 2021 Jun 29.

Institute of Nutrition Josué de Castro, Federal University of Rio de Janeiro, Av Carlos Chagas Filho, 373, CCS. Bloco J, 2° andar. 21941-902 - Ilha do Fundão, Rio de Janeiro, Brazil.

Background: Inadequate gestational weight gain (GWG) is associated with adverse outcomes in maternal and child health and can be enhanced by social inequalities, such as lower education and household food insecurity (HFI). Women are more vulnerable to HFI, which has been associated with negative health effects for pregnant women during the prenatal and puerperal periods, particularly in regard to the aggravation of pregnancy risks. This study investigated the association between sociodemographic characteristics and HFI with respect to adequacy of total GWG among women with high-risk pregnancies. Read More

A randomized controlled trial of daily weighing in pregnancy to control gestational weight gain.

BMC Pregnancy Childbirth 2020 Apr 16;20(1):223. Epub 2020 Apr 16.

University of Queensland, St Lucia, Queensland, Australia.

Background: Excessive gestational weight gain is a modifiable risk factor for the development of obstetric and neonatal complications, and can have a lifelong impact on the health of both mother and offspring. The purpose of this study was to assess whether in addition to standardized medical advice regarding weight gain in pregnancy (including adherence to the Institute of Medicine (IOM) guidelines) (IOM (Institute of Medicine) and NRC (National Research Council, Weight Gain During Pregnancy: Re-examining the guidelines, 2009)), the addition of daily weighing would provide a low cost and simple intervention to reduce excessive weight gain in pregnancy by maintaining weight gain within the target range.

Methods: Women presenting for antenatal care to a secondary level hospital were randomised to routine care or daily weight monitoring. Read More

Eating behavior and weight gain during pregnancy.

Eat Behav 2020 01 21;36:101364. Epub 2020 Jan 21.

Department of Preventive Medicine, University of Tennessee Health Science Center, United States of America. Electronic address:

Objectives: Little is known about the relationship between eating behavior and weight gain during pregnancy.

Purpose: Our objective was to assess the relationship among self-reported cognitive restraint, disinhibition, and hunger, and excessive gestational weight gain (GWG) as defined by the Institute of Medicine's (IOM) 2009 guidelines. Based on previous research examining eating behaviors and weight gain in non-pregnant women, we hypothesized that excessive GWG would be related to higher cognitive restraint, higher disinhibition, and higher perception of hunger.
